My annoyances with Epic’s store are generally limited to Fortnite pop-ups and forgetting I even had games installed there, but then I play games on a big desktop PC. If you’re using a laptop, you might want to keep an eye on the store, and in particular what it’s doing to your battery.
Some testing from PC World has found that, if you’re using the store and have your laptop unplugged, Epic’s marketplace can be an enormous drain on your battery, even if it’s simply running in the background.
On one device, a Surface Pro 7+, its battery depleted 20% faster just by having the Epic store open, while on a Surface Laptop 3 it was drained 8% quicker. Epic told the site in response that, “In general, we are actively working to improve the performance and reduce the power consumption of our launcher.”
While that happens, if you’re playing on a laptop and need to use Epic’s store, maybe keep it near an outlet. Oh, and note that the same tests showed that Steam had practically no effect on the devices’ batteries.
